Dredging to remove harmful chemicals from a length of the Fox River in the Green Bay area is set to start April 2, but a company paying for much of the cleanup is putting the brakes on work this year.
Appleton Papers Inc. has told the U.S. Department of Justice that it wants to resolve who is financially responsible for the massive cleanup before it resumes the work.
The potential delay could put the cleanup of polychlorinated biphenyls from the river further behind schedule. Last year, Appleton Papers and NCR Corp. stopped work in late July over the same dispute. Dredging operations could have continued for several more months.
The cleanup is the largest of its kind in the United States, and according to court records, the cost of removing PCBs from river sediment will exceed more than $1 billion.
The aim is to stop the flow of PCBs into Lake Michigan and eventually make fish in the Fox safe to eat.
